  1. I tried with turning off "Remove empty first layers" but it just brought the object down to the plate I got it to work only when Remove empty first layers was off, no support, and Use adaptive layers was off. Otherwise it would still drop it to the plate. I still can't get it to work without turning Adaptive Layers off. Without support and deleting in gcode. With the gcode volume path visualizer it makes it a vertically mirrored pointed shape, from an orthographic view, but the path still goes past the mesh outline below and not to it above. Even though it follows the shape and a rectangular cross section view of an extrusion would also represent it, it's still different on each side. I found turning on Adaptive Layers shows that it slices outside and not to the stl mesh part skin, as shown in these. But turning off Adaptive Layers makes it go right up to the stl mesh skin. No gaps to the perimeter. Shown here. G_Tee_T2-2.0_tee float 13m Use Adaptive Layers.gcode G_Tee_T2-2.0_tee float tpu 10m 5w 30p 0.2L 220 30-15-22ow e3.gcode
  2. Yeah I checked and have Slicing Tolerance set to middle. Yeah I saw the asymmetry in the side view from the kind of triangular legs, I was talking about the displayed gcode path going outside and inside the mesh displayed. I can see the pictures lower resolution when posted so you can't really see it. So I'll post more close up I see the g code paths go out pretty far on the bottom of the mesh outline, and not quite all the way to the side and mesh outline in the top. So I'm wondering if there is a middle slicing tolerance for this as well or how much it's tolerance is to keep from running into any base part printing on. You can see it from the side, and this is with 0.2mm layer height so not crazy small. G_Tee_T2-2.0_tee 13m .2l.gcode
  3. I haven't yet tried in Cura 5.0 so we'd have to give it a go. Hope it still works or other good addition. And it slices with layers biased more to the bottom and going past mesh there, and not all the way to the top of the mesh for layers on top. I've got slicing tolerance to middle. Does anyone know if there's another way to change this or know how much it is and how to get it to slice mostly in the middle of the mesh outline top and bottom? I'd like to know as much as possible to plan for squish or it running into the support base or gap in between. It seems inconsistent and depends on layer height and mesh height when I move it up and down and re slice, so just built in software.
  4. Haha thanks Greg. I was thinking about deleting supports below in gcode but didn't want to have to create a small object below the tee. The adding exclusion and changing to support works well. And I forgot about the relative extrusion that's great catch. And I couldn't get it to work without reducing minimum support area and other settings so good instructions. It kept dropping to the plate anyway. Ideally I'd also like to figure out a way that I can do this and have it slice without going in and deleting g code lines every time. Because now with this I can do it and it slices the floating without being connected to the support touching the build plate. If there's a setting that will just allow this without having to have the support there separate touching the build plate, that would be very good. Or making the support height too small to slice or width to small to make a path but Cura still thinks it's meeting the values and slices the floating model. So far I've got the support height at .1mm and it won't let me go shorter and object at .3 with layer .2 and it still has the first layer. Oh shoot I just got it to not print the support by turning off adaptive layers. That's great. But I'd still like to have adaptive layers for more detail and smoothness on the almost horizontal parts, so if anyone still can know how. And would like to not have to add and shrink support every time. But this is great in the mean time. Yeah pretty frivolous for just a golf tee, but I'm trying to experiment so I can get it going for a lot of things to print anything with a round or small surface area bottom to keep it from giving a flat spot or slowing down all the way. Then we could print any sphere shape or rounded object without compromise or splitting. Have a pre made aluminum base for lots of prints of the same part. Or print a base support out of plastic that melts at higher temperature, like petg or pc, then print pla part on top to stick but not bond to the support base. Yeah it's hard to tell with just a picture. I was able to slice with it touching the plate and it filled and was solid. I'll put the file below.

  5. Hey everyone. I'm experimenting with using supports that were made before an item is printed that are fixed and bonded to the bed. I'm trying to slice a floating object and it gives 0 minutes and 0 material used. How do I get it to print the floating part and put in the print and travel moves for a non-touching object? And obviously don't want it traveling through the non-seen support. I've got Don't drop the object to the build plate and Remove empty first layers on. Thanks
